Abstract: This fact sheet presents population data by generation and by state, identifying which generation represents the largest share of the population in Mountain West states. The data are derived from the Brookings Institution report, "Baby boomers are turning 80: A closer look at the generation that reshaped America," by William Frey. This fact sheet compares the 2024 population of each generation, from Pre-Baby Boom to Gen Alpha, to identify the largest generation in each of the five Mountain West states: Arizona, Colorado, Nevada, New Mexico, and Utah.
